Downtime cut
May 1st 2004

Swapping from pneumatic power to an electric cylinder supplied by Hoerbiger-Origa, coupled with a bit of a redesign, has slashed maintenance time on a slitter positioning system for St Regis, Kemsley paper mill near Maidstone.

Watching a cylinder changeover procedure, Hoerbiger-Origa realised improvements could be made to the way in which the cylinder is mounted onto the machine. It suggested that a rail should be built onto the machine with Special GDLF External Guide carriages mounted onto this to allow the cylinder to slide into and out of position.

This would reduce the mounting/demounting task to a two-man, one-hour operation and represent a large saving in downtime.

The GDLF guide is based on bearings used internally in the BHD cylinders, while a Control Techniques UNI SP servomotor was specified as the prime mover.
